Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Connect the Components: Follow the circuit diagram to connect the water sensor, LED, and Arduino. Upload the Code: Open the Arduino IDE. Copy and paste the provided code into the IDE. Select the ...

Automated Soil Moisture Monitoring System Welcome to the Automated Soil Moisture Monitoring System project! This system uses an Arduino, a soil moisture sensor, and an LCD display to monitor the ...

We connected $\\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The sensor was ...
